Abstract
A Sezawa wave storage correlator was used to implement an adaptive filter for noise cancellation. The filter reduced the level of a 150 MHz CW jamming signal by 26 dB and a broadband Sezawa wave convolver was used to compress an underlying chirp signal. The tap weights are determined in 40 to 100 ¿s, depending on the jamming signal power and feedback gain.
